Add the full crosstool-NG sources to the new repository of its own.

You might just say: 'Yeah! crosstool-NG's got its own repo!".

That means I'm putting backups in place in the afternoon.
That also means we've lost history... :-(

+      If HOST_CC ends with a dash (-), then it is considered to be the
+      prefix to gcc (eg. x86-pc-linuc-gnu-).
+      If it is empty, it is formed by appending '-gcc' to HOST.
+      Else it is considered to be the complete name of the compiler, with
+      full path, or without path (provided that it can be found in PATH).
